12.1 Toxicity
Methyl palmitate's production and use as a synthetic intermediate may result in its release to the environment through various waste streams. Methyl palmitate is found naturally as a flavor component of some foods. If released to air, a vapor pressure of 0.00006 mm Hg at 25 °C indicates methyl palmitate will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase methyl palmitate will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 20 hours. Particulate-phase methyl palmitate will be removed from the atmosphere by wet and dry deposition. If released to soil, methyl palmitate is expected to have no mobility based upon an estimated Koc of 18,000. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 0.009 atm-cu m/mole. However, adsorption to soil is expected to attenuate volatilization. Methyl palmitate is expected to rapidly biodegrade in aerobic soils as suggested by results of screening studies. If released into water, methyl palmitate is expected to adsorb to suspended solids and sediment in the water column based upon the estimated Koc. Methyl palmitate is expected to rapidly biodegrade in aerobic waters. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization h
